getSize(T t,
java.lang.Class<?> type,
java.lang.reflect.Type genericType,
java.lang.annotation.Annotation[] annotations,
MediaType mediaType)
Called before writeTo to ascertain the length in bytes of
the serialized form of t.

genericType - the type of object to be written, obtained either
by reflection of a resource method return type or via inspection
of the returned instance. GenericEntity
provides a way to specify this information at runtime.

annotations - an array of the annotations on the resource
method that returns the object.

getSize

Called before writeTo to ascertain the length in bytes of
the serialized form of t. A non-negative return value is
used in a HTTP Content-Length header.

Parameters:

t - the instance to write

type - the class of object that is to be written.

genericType - the type of object to be written, obtained either
by reflection of a resource method return type or by inspection
of the returned instance. GenericEntity
provides a way to specify this information at runtime.

annotations - an array of the annotations on the resource
method that returns the object.

Write a type to an HTTP response. The response header map is mutable
but any changes must be made before writing to the output stream since
the headers will be flushed prior to writing the response body.

Parameters:

t - the instance to write.

type - the class of object that is to be written.

genericType - the type of object to be written, obtained either
by reflection of a resource method return type or by inspection
of the returned instance. GenericEntity
provides a way to specify this information at runtime.

annotations - an array of the annotations on the resource
method that returns the object.

mediaType - the media type of the HTTP entity.

httpHeaders - a mutable map of the HTTP response headers.

entityStream - the OutputStream for the HTTP entity. The
implementation should not close the output stream.

Throws:

java.io.IOException - if an IO error arises

WebApplicationException - if a specific
HTTP error response needs to be produced. Only effective if thrown prior
to the response being committed.
